Girtin and Loshak, op. cit., p. 136 suggests that the present drawing is after one by Edward Dayes, dated 1792, which was sold in these Rooms, 14 March 1952, lot 221. The drawing by Dayes was taken from an 'on the spot' sketch by James Moore, executed on 22 May 1789. The subject matter reflects the antiquarian interests of Moore, Girtin's first patron, while stylistically, the influence of Edward Dayes, to whom Girtin was apprenticed at this time, can be seen: Davies, loc. cit., notes the similarity between the present work and the Dayes drawing, 'It would be difficult to find any other instance of so perfect an assimilation of a master's methods which is neither a copy nor a servile imitation, but simply an independent work done in a manner and with something more of the skill of the master'.
